Steve. There were no problems at all. It was an absolute pleasure. I was not sure which tool to load first until I opened the G code and then every thing was clear. Feeds and speeds were good. The holding jig worked a treat, blank sizes were good. I did not realize that the final top face...

Here are a few photos of the final article and my mill. The concept from the builders point of view is excellent. The ens result is looks really cool. Is there any chance that we will have the importunity to test a few more components for this little gem? if the security issues could be fixed...

I have been giving this a try. Every thing works fine so far except I did not have Mach 3 set to stop for a tool change. You might want to mention that in your instructions. I have the basic shape of the head finished,and am starting the fins. The basic concept is awesome. Far better...

I am sorry Steve I meant "if i ran it through a simulator" not you. Bad South African English!I look froward to what you produce. Thanks Buchanan

I would be very happy to run a test for you on your engine head. I have a home build CNC (Modified Harrison horizontal mill and Mach 3) in Metric so could check conversion from Imperial as well. Keep going,and start a thread in a forum for each part or file for everybody to go to for...

Steve It is an excellent idea. Try it on something simple like a flywheel and put it out there and then wait for the complaints/compliments. Don't stop please. Buchanan

Here are photos of the second tool path omitted in the last post as well as photos of the plugs and the machine used. The vacuum cleaner sucks the dust through the bottom of the vice.

Brian S You asked what cutters I use, A 10mm diameter and 32mm long cutting edge wood router bit and a 21mm diameter 2mm thick woodruf cutter. I have attached photos of the cutters and also the tool paths I use. There are three basic operations. 1 The rough bock is held in a vise and...

They are great fun to make and you can test your skills and the limits of the materials to the limit. I have turned many on lathe over the years but now make them on a small CNC mill with two cutters and 3 G codes to produce 4 blocks in a 65mm square wood block. It is simple enough to draw out...

Ron I should read your post more carefully. I see you were referring to the diamond files and I replied about the ruby files. look like they would fit in a Diprofile type reciprocating hand piece But i may be wrong again. Buchanan

Hello Tom. The files arrived today. they are perfect, Thanks. Ron. To my knowledge they are mainly used in watchmaking, held by hand, as a normal file.They give a very fine finish,almost a polish on hardened steel.They also keep a sharp or square edge very well so that you can finish a...

Hello . I have been through a similar process with a mill I bought for my father and have been very pleased with the overall improvement. Also working on a cnc conversion for him. Regards Buchanan

Terry. I have watched most of your previous thread and all of this one and would like to say how much I enjoy all you do.I especialy like your self imposed quality controls not to mention your beautiful wrkmanship. I also enloy your depatures from the set plans and really like the results on...

Hello Austin . I would like to say that I think you have a very good balance in this forum. Keep it just like it is. Deryck

Yes you can cut as long a key way as your arm muscles hold out for.I have done this many times. you will need some way to adjust your tool hight and the tool will need to be very firmly clamped. If your lathe is small you may need to make your tool narrow and reset its hight to get the keyway...

Is there any body out there that has reverse engineered a brushless motor into a alternator. Modern electronic regulators can look after the rest.That should give high eficiency and low maintanance. India used to make a comercialy available hot air engine which powered a cooling fan up to about...

Brian .What about an helical screw lift for your ball machine,low constant torque. visualy interesting. put it in a glass tube or guide the balls with a couple of rods. Deryck

In my company we try to give good old fasiond service. One gets a kick out of sending sombody away happy when they came looking for somthing that they did not have much hope in finding. It makes for loyal customers. All appreciat that kind of service but some do seem to take unfair advantage of...

Draw-Tec. Give me a few moments to finish my mill and i will take you up on your offer. Thanks Buchanan

Thanks Draw Tec. I will keep waiting. I think I have a lot to learn abour CNC. I have been cutting metal for 32 years but there is so much new in CNC. Buchanan
